1) Over blinding (Put in a blind when one is already present). In a traveling
blind game, this could mean someone putting in an optional blind in addition
to the mandatory blinds. In a game without mandatory blinds, this would be
blinding a pot (putting in a blind) after someone else has killed it. (To
put in an over blind is sometimes called to kill.).

2) Playing at a higher limit than the house has set for the game, usually
for the purpose of paying time to the house at the nominal rate for the game.

For example, playing 8-limit stakes in a 6-limit game, or playing 4-8 in a
3-6 game.

3) Playing, among players who agree, at higher
limits then those who don't have dropped.
